Saw a truck around town today with a ridiculous lift kit and chunky off-road tires that were clearly much larger than factory standard, and it got me thinking; if you install this kind of modification in a car, do you need to adjust the speedometer to compensate? What about the odometer?
My logic is the only absolute measurement the car has is how fast the wheels and drive shaft are turning, so presumably there is some sort of multiplier - 1 revolution = X meters - that is then used to show speed and track distance travelled, but that factor would need to change if the circumference of the tires did
Well, I’d argue it’s not a blanket “no”. I’ve owned 9 crotch rockets and all? Of them had speed sensors on front sprockets. A lot of similar or the same designs within, so surely it’s off ABS rings if they’re newer, but a fair few of them have had speed deviations because of that
So it’s not a blanket “same with motorcycles” either then ;)
You’re absolutely right!
I don’t know of a single car that it wouldn’t affect, but there could be some using a gps speed instead? Sounds like a bad idea to me
